摘要： In a method of manufacturing a piezoceramic multilayer actuator (10), a plurality of green layers is provided, wherein the green layers are to be converted to piezoceramic layers (12) with a piezoceramic material in a subsequent step of heating. A security layer material mixture with a second material (32) and particles (30) embedded in the second material (32) is provided, wherein the particles (30) have a third material different from the first material and different from the second material (32). The security layer material mixture is laminated between two piezoceramic layers (12), thereby forming a green stack. The green stack is heated to a sintering temperature, wherein the green layers are converted to the piezoceramic layers (12), and wherein a chemical reaction of the third material degrades the mechanical connection of the piezoceramic layers (12) by the security layer (20).

摘要： In a method and device for polarizing a piezoelectric actuator according to which high-frequency pulse voltages can be used for polarizing the actuators an actuator to be polarized is mounted between two retaining elements while connected in series to a second piezoelectric actuator. The retaining elements provide the actuator (1) with a desired pretension. A compensating element compensates for changes in length of the actuator (1) so that even in the event of high-frequency pulse voltages and thus high-frequency changes in length, the pretension can be maintained within a desired range of values. Preferably, the second piezoelectric actuator has the identical design of the first actuator and is polarized with the first actuator. This enables two piezoelectric actuators to be simultaneously polarized during a polarizing process.

摘要： A piezoelectric actuator includes a piezoelectric bending transducer, the first end of the bending transducer may be pivoted, while its second end, which is opposite to the first end, may be movably supported in a longitudinal transducer direction. Given a simultaneously large deflection path or bending lift, the actuator may attain a high restoring or working force. Thus, in the case of a valve piezoelectrically actuated by such an actuator, the sealing effect of a valve channel, which is closed or to be closed, may be significantly increased.
摘要翻译：压电致动器包括压电弯曲换能器，弯曲换能器的第一端可以枢转，而与第一端相对的第二端可沿纵向换能器方向可移动地支撑。给定同时较大的偏转路径或弯曲升力，致动器可获得高的恢复力或工作力。因此，在由这种致动器压电驱动的阀的情况下，可以显着增加关闭或关闭的阀通道的密封效果。
